I get have exactly what I want in my amp...resistors, capacitors, hookup wire, custom transformers, tube sockets, chassis design, connectors, etc. It is based on amp I already own and love, but taken to the extreme. I'm not doing this without guidance because I have the designer himself involved in this project. I can get the amp of my dream at a fraction of the cost of an equivalent commercial product. Every commercial product I've seen, unless you are willing to spend over $80K+ is a product of compromise. Even in some of these products, you have to wonder where the money was spent.
